Had a look at this---looks simple, but it may want to download nodejs modules during the build, which will make it a lot harder to package. We cannot download bits during the rpm build, we must package everything that's required separately and make it all available offline.

So I'd recommend folks first try to just build it from source using something like pip install . in a virtual environment to see what it does. if it does try to run npm/yarn etc. and download nodejs modules, I'd leave this alone for the moment.
